JsMacros Ruby

by grepsedawk

JsMacros Ruby lets players write JsMacros macros in Ruby instead of JavaScript, using .rb files placed in the macros folder.

FabricClient-side onlyMIT License26.1 – 26.3

What it does

Macros written in Ruby are picked up automatically and bound to triggers the same way JavaScript macros are. Scripts execute in a JRuby interpreter and can call the complete JsMacros interface. The mod is a companion to JsMacros Reloaded and adds no features of its own beyond the Ruby language support.

JRuby is bundled with the mod, so no separate Ruby installation is needed. The mod runs on the client only, so servers do not need it. It is published for Fabric across five release versions in the 26.1 – 26.3 range, with the latest file, 1.1.0+fabric, built for 26.3. The code is released under the MIT License and is not open source.

Installation requires Fabric Language Kotlin and JsMacros Reloaded 2.0.0 or newer. Players install JsMacros Reloaded first, then drop .rb files into the macros folder.

Key features

  1. Ruby macro files

    Macros are written as .rb files and placed in the JsMacros macros folder, where they are loaded like other macros.

  2. Automatic trigger binding

    Ruby macros are bound to triggers in the same way as JavaScript macros, so no extra setup is needed per script.

  3. Bundled JRuby runtime

    The JRuby runtime ships inside the mod, so a separate Ruby install is not required to run scripts.

  4. Full JsMacros API

    Ruby scripts have access to the complete JsMacros API used by JavaScript macros.
